In a poetic text resembling a series of haiku, the particular habits and grace of one slim, independent but affectionate cat are vividly evoked (``He goes under. He goes through. He goes everywhere that is too narrow for me''). In illustrations as spare and carefully honed as the words, Davie depicts a little girl and her yellow-dappled pet during a typical companionable day. A joyful, perceptively observed vignette. (Picture book. 4-8)
